Since taking over from Steve Tambellini in April 2013, MacTavish has been among the most active general managers in the NHL.
His mandate is to expedite the Oilers' rebuilding process without sacrificing their young core.
In an effort to improve a team that finished at the bottom of the Western Conference standings last season, MacTavish brought in wings Benoit Pouliot and Teddy Purcell, while adding to his blue line with defensemen Keith Aulie, Mark Fayne and Nikita Nikitin.
"For us, size was an issue," MacTavish said. "We knew we needed to get bigger and both of these guys are bigger. Teddy Purcell has quite a bit of talent; I think there is still some untapped upside in him that we're hoping to discover.
